    Refrigerant Refrigerant leaking from an open or broken circuit may cause asphyxiation, severe frost damage, arrhythmia, or neurological symptoms. If you suspect a refrigerant leak, leave the area immediately, and seek fresh air. Help and warn others. The unit includes a hermetically sealed refrigerant circuit filled with refrigerant R-410A. Refrigerant R-410A is a mixture of two refrigerants: HFC-32 (R-32, difluoromethane) and HFC-125 (R-125, pentafluoroethane).

The Heating buffer sensor setting determines which method is used. Each circuit’s equipment is selected under the relevant circuit. Not connected The heat pump is connected directly to the building’s heating system without a buffer tank.
  • Page 39 **An example of typical value adjustments: 1. If the room temperature is too cold when the outdoor temperature is −10 °C, slightly increase the flow water setpoint at outdoor temperature points −13 °C and −7 °C. 2. Wait for at least two or three days to see if the change has made a difference. 3.
  • Page 40 → ADDITIONAL HEATING Freezing protection only The electric heater will be switched on only when heating water temperature falls below +5 °C. The freezing protection function monitors the temperature in the condenser, buffer tank, and the heating circuits. Once the temperature exceeds +10 °C, the electric heater will be switched off.
  • Page 41 Device settings → Service → Hot water → Additional heating If any of the settings specified below have been selected, the system can switch on the electric heater during DHW heating (as long as the legionella function has been enabled) when the compressor reaches the bounds of its operating envelope and is consequently switched off.

  • Page 43: Operation

    5 Operation 5.1 Heat pump operation The system’s connection diagrams are provided as a separate document. The heat pump collects heat from the fluid in the brine circuit and releases the heat collected through a condenser and into heating water. In addition to the heat pump itself, CUBE heat pump units include an in-line heater for supplementary and backup heating.

Whenever the building’s domestic hot water needs heating, space heating will be suspended until domestic hot water has been heated to a sufficient temperature. Domestic hot water tank heating will start when the DHW tank temperature (minus the switching difference) falls below the domestic hot water target temperature.

    6 Technical data 6.1 Heat pump technical data The performance between different units may vary. This variation is due to a wide number of factors, such as the properties of the fluids used in the circuits, fouling of the heat transfer surfaces in the condenser and evaporator circuit, flow rates, individual differences between compressors (standard EN 12900) as well as refrigerant circuit charge and adjustments made to the refrigerant circuit during installation.
